Reviewed: 2018 Cadillac CT6

Last year Cadillac sent us a new version of their CT6 flagship sedan.Their first full-size car since the 1996 Roadmaster, it is worthy to be called “The Standard Of The World”. It is longer and wider than the CTS, with comfortable seating and impressive insulation from the outside world. The 2017 model was a far cry from Cadillacs of recent years, so we had no idea they had an ace up their sleeve.

Last week we were surprised to see a 2018 CT6 and wondered what made it different. An infrared sensor on the steering column was the first hint, but more on that later. The wheels were a new design, and the surround view cameras now have high-pressure washer nozzles to prevent the dreaded Cadillac Cataract…. It’s nice to see around you when parking a Nimitz-class carrier.

Under the hood is the same twin-turbo 3.0 liter V6. It is nice to drive a luxury car that doesn’t insert fake engine noise into the audio system because this car has no less than 34 speakers. The Bose Panaray was developed specifically for the CT6. It is the best factory audio we’ve ever experienced. The other main feature that was not offered in 2017 was Supercruise.

GM’s first production autonomous driving system, it was capable of navigating 10 miles of this nation’s most dangerous interstate. Instead of bouncing between the limits of each lane, the CT6 was as sharp as a knife. It makes sure you are looking ahead thanks to the IR camera mentioned above. It is even capable of cruising at triple-digit speeds…not that we would ever attempt such tomfoolery.

Compared to a 2018 Mercedes-Benz S550, Supercruise is much more lenient on the driver. It is very relaxing after a long day when you realize the front seats have automated ventilation. The car senses your body temp and actively varies the fan speed to keep you comfy. Another great upgrade is version 2.6 of the CUE system. It has haptic feedback for most functions along with the ability to change the apps displayed on the home screen.

A steering wheel light bar and cluster icons indicates the status of Super Cruise™ and will prompt the driver to return their attention to the road ahead if the system detects driver attention has turned away from the road too long. Super Cruise is asking for the driver to resume control of steering (flashing red light bar) in this image.

The unibody is mostly aluminum with high strength steel for the safety cage. It rides on magnetic suspension and augmented by rear wheel steering. It doesn’t feel as big as it is when the turbos spool up, reaching 60 mph in 5.2 seconds. When you consider the starting price of $54,500, the CT6 is a bargain. Aside from the 404 horsepower twin-turbo V6, Cadillac also offers a 2.0L turbo hybrid. It has a 110v plug with built-in charger and it offers 31 miles of electric range.
